本文在总结企业物流系统需求分析的基础上,结合模型开发方法,分析并设计了物流管理信息系统的各个功能子系统的过程模型、数据逻辑模型、数据概念模型以及用户界面。 - Because the vigorous market competes and data warehouse give the business enterprise the high the bigness value , the high leaders of the material limited company of the two bureau of china ' s train draw a conclusion to establish the decision support system , increasing the competition ability of the business enterprise with more science more completely of decision support . we have investigate and understand the need of the leader , the manager of sale department and employee . according to the general principles that data warehouse design , we select the sale topic to establish prototype design
对于该公司的领导、销售部门经理、以及员工的调查与需求了解，以及按照数据仓库开发的一般原则，首先选取商品销售主题进行快速原型设计，从第三段开始以销售决策系统设计开发为出发点，按照数据仓库开发的一般原则和步骤，逐步探讨了基于数据仓库技术的中铁二局物资有限公司销售决策系统的项目需求分析、系统软硬件结构设计、概念模型设计、多维数据逻辑建模、数据抽取、转换、清洗和装载设计、多维分析服务器的设计以及前端数据分析工具的设计与开发等问题。 - Results showed that , attribute data obtained by this way avoided deficiency of polygon overlap way , as a result , the logistical consistency between map data and attribute data reached over 90 % on average . database pivot precision was 0 . 18mm , data quantity during manipulation was decreased greatly , data treatment was more convenient , computation velocity was boosted greatly . workload of map and table pretreatment and edition was mitigated on large scale , spatial data precision was increase
研究表明：用该方法获得的属性数据，避免了多边形叠加方法的不足之处，能使图形数据和属性数据逻辑一致性平均达到90以上，数据库点位精度达到0 . 18mm ，且操作中图层数据量大大减小，数据处理更为方便，运算速度大为提高；减轻了图表预处理和编辑的工作量，使空间数据精度提高。 - In the general model there are many factors effecting the algorithm of task matching and scheduling , such as data dependencies among tasks , processor ' s processing speed , topology of network connectivity , communication protocol and bandwidth , volume of transferring data , etc . in each model , we proposed two genetic algorithms for task matching and scheduling , one is for single decomposed task , the other as a cga is for multiple independent tasks
一般模型中任务分配与调度受到系统多种因素的影响，如任务间的数据逻辑关系、各处理机的计算速度、网络拓扑结构、节点间通信机制以及通信波特率、数据流量大小等等。在考虑上述影响因素的基础上，分别提出单任务分配与调度的遗传算法和独立多任务分配与调度的共同进化算法。
